ٱلَّذِينَ ضَلَّ سَعۡيُهُمۡ فِي ٱلۡحَيَوٰةِ ٱلدُّنۡيَا وَهُمۡ يَحۡسَبُونَ أَنَّهُمۡ يُحۡسِنُونَ صُنۡعًا ١٠٤
Al-ladhīna ḍalla saʿyuhum fil-ḥayātid-dunyā wa hum yaḥsabūna annahum yuḥsinūna ṣunʿā.
[They are] those whose effort is lost in worldly life, while they think that they are doing well in work."
